Evaluating LLM-Based Test Refactoring with a Behavior-Preserving Composite Metric
Wendkûuni C. Ouédraogo, Yinghua Li, Xueqi Dang, Paweł Borsukiewicz, Xin Zhou, Anıl Koyuncu, Jacques Klein, David Lo, Tegawendé F. Bissyandé
Large Language Models (LLMs) are increasingly used to refactor automatically generated unit tests, which often achieve high coverage but suffer from poor readability and maintainability. Evaluating such refactorings remains challenging, as existing metrics either penalize beneficial edits or overlook readability. We introduce CTSES, a composit(...)

LongTest: Test Prioritization for Long Text Files
Xueqi Dang, Yinghua Li, Wendkuuni C. Ouedraogo, Maxime Cordy, Mike Papadakis, Jacques Klein, Tegawende F. Bissyande, Yves Le Traon
Text classification is a fundamental task in natural language processing (NLP) that involves assigning predefined labels to text files. While existing research has primarily focused on short texts (e.g., social media posts), the classification of long texts, such as legal documents and medical records, has gained increasing attention due to th(...)

Toward an Operational Intrusion Detection and Prevention System for SDN-IoT: A Cascaded Deep Learning Approach with Automatic Mitigation
Yacouba OUATTARA,Yaya TRAORE, Abdoul Razak TARPAGA
Abstract—The convergence of software-defined networking and the Internet of Things widens the attack surface of connected networks
and calls for defenses able to detect attacks at the controller's vantage point and to block them there. Earlier work compared deep
architectures for denial-of-service attack detection and opened two perspectives(...)

Replacing Training with Reasoning: Reinterpreting Classic ML Pipelines with LLMs
Marco Alecci, Jordan Samhi, Tegawendé F. Bissyandé, Jacques Klein
Large Language Models (LLMs) are increasingly used in software engineering tasks due to their strong performance across diverse applications. In this paper, we ask a fundamental and novel question: To what extent can LLMs replace traditional machine learning pipelines that rely on labeled data, feature engineering, and retraining?

Experimental Performance Evaluation of a Low-Cost Cylindrical Solar Concentrator for Thermal Cooking Applications in a Tropical Climate
Prince Abdoul Aziz Honadia , Bouto Kossi Imbga and Thierry Sikoudouin Maurice Ky
Access to clean and affordable cooking energy remains a challenge in developing regions, particularly in sub-Saharan Africa, where traditional biomass fuels are widely used and are associated with environmental and health concerns. Solar cooking provides a renewable alternative; however, the practical application of low-cost cylindrical solar(...)

Characterization of raw clay from N'Djamena (Chad) used in water treatment: the case of lead (Pb) in aqueous systems
Constant Allaramadji Ngarmadji, Youssouf Sawadogo, Joël Samba , Moustapha Sawadogo, Kassoum Barry, Mohamed Seynou, Lamine Zerbo
This study evaluates the potential of a natural clay from N’Djamena (Chad) for removing Pb²⁺ ions from aqueous solutions under static conditions. The adsorption performance was interpreted using Langmuir and Freundlich isotherm models. Mineralogical characterization classified the raw material as a clay soil, predominantly composed of kaolinit(...)
